A p ication filed May 14,

To all whom it may concern...-

Be it known that I, \VILLLAM C. SPEER, a citizen of the United States,residing at Wright, in the county of Ford, State of Kansas, haveinvented certainnew and useful Improvements in'Snowplows; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This" invention relates to new and useful improvements in plows andparticularly to snow plows.

One object of the invention is to provide a novel and improved snow lowin which the shovel thereof can be easi y and quickly raised and loweredby the operator and held in such positions.

Other objects reside in the novel and particular construction andarrangement of the various parts of the device whereby a strong anddurable, as well as effective device of this character is produced.

Other objects and advantages will be apparent from the followingdescription when taken in connection with the accompanying drawings.

In the drawings;

Figure 1 is a side elevation of a snow plow made in accordance with theinvention. Figure 2 is a top plan view of the same.

Figure 3 is a vertical longitudinal central sectional view taken on theline 3-3 of Figure 2.

Figure 4 is a bottom plan view of the device, showing the manner ofbracing the various parts of the plow.

Referring particularly to the accompanying drawings, 10 represents anaxle on the ends of which are rotatably supported the ground wheels 11.On the outer ends of the axle,, outwardly of the hubs of the wheels 11,are the collars 12, each having a vertical extension 13 to which issecured one end of a brace 14. Secured to the center of the rear face ofthe axle is a U-shaped bracket 15, and pivotally mounted in this bracketis the forward end of the draft pole 16, inclined braces 17 beingsecured to the opposite sides of the pole, at their rear ends, andpivotally connected to the axle at their forward ends, the latterconnection being shown at 18. Rigidly secured to the lower face of theaxle, at points below the pivotal connections 18, are the rear ends1920. Serial No. 381,322.

.of the arms 19, which extend forwardly from the axle, and supported onthe forward ends of these arms is'the double moldboard plow 20. A crossbrace 21 connects the intermediate portions of the arms 19. On thecenter of the upper face of the axle 10. there is secured the verticallyarranged U-shaped bracket 22 in which is pivotally supported theintermediate portion of the longitudinally extending lever 23. A'U-shaped bracket 24% is secured to the center of the upper face of thecross brace 21, and pivotally supported in this bracket is the forwardend of the lever 23. The upper end portions of the braces 14 are curvedand secured to the inner faces of the moldboards of the plow. A crossstrap 25 is secured to the intermediate portion of the under face of theplow, while a reinforcing strap 26 is secured to the lower face of theforward or snow engaging edges of the plow. Longitudinal straps 27 aresecured to the side edges of the moldboards, whereby the plow iseffectively braced and strengthened.

On the rear end of the pole is secured a casting 28, and rotatable inthe rear end of the casting is the upper portion of the pintle 29 of thecaster 30. The upper end of the pintle 29 is provided with a handle 31,which is grasped by the driver to turn the caster, for the purpose ofsteering the plow. Secured on the rear of the pole, and resting on thecasting, is a platform 32, on which the driver stands, while driving theanimals, said animals being hitched to the draft means 33, which aremounted adjacent the front of the platform, and on the pole. A trussbrace 34 is mounted on the upper side of the lever 23, whereby saidlever is prevented from bending or breaking while being presseddownwardly, as in elevating the plow.

Mounted on the intermediate portion of the pole is a bracket 35, androtatably supported on this bracket is a grooved wheel 36. A chain 37 issecured at its forward. end to the lever, and after passing through thebracket, in engagement with the grooved wheel, has its rear end securedto the upper end portion of the pivotally supported lever, which ismounted on the side of the pole, forwardly of the platform, and withinconvenient reach of the driver. The lever 10 has a pawl 38 which engageswith the notched segment 39, also mounted on the side of the pole. Whenthe plow is to be elevated, as when the machine is to he moved from oneplace to another, the driver depresses the rear end of the lever 23,which raises the plow above the ground, the driver then pulling thelever 40 back and locking the same with its pawl, thus holding the lever23 depressed and the plow elevated at the front of the machine.

It will, of course, be understood that the animals are so hitched to themachine that the machine is pushed forwardly.

What is claimed is:

A snow plow including a push pole, a frame pivotally supported on theforward end of the pole for vertical movement, ground wheels on thesides of the frame, a
